loneliness

loneliness will bring some people to do things they normally would not do. this is very sad but true. what makes some people so lonely they will do desperate things whereas others who are lonely will not stoop so low?  i don't pretend to know the answer to this one. as with all things one can't judge another until one has been in his/her shoes. loneliness can be so pervasive. its hard to understand its effects unless one has had the experience.
